The healthcare provider is preparing to administer an intravenous (IV) medication to a client. Which action should the healthcare provider take first?

Correct Answer: B

Rationale: Checking the client's allergy status is the priority before administering any medication, especially intravenously. This step helps identify any potential allergic reactions and prevents harm to the client. Verifying the client's identity using two identifiers is important but not the first step in medication administration. Preparing the medication for administration and administering the medication at the prescribed rate come after ensuring the client's safety by checking for allergies.

Correct Answer: D

Rationale: The correct answer is D. Increasing potassium intake can lead to hyperkalemia, especially in clients taking ACE inhibitors like enalapril. Hyperkalemia is a potential side effect of ACE inhibitors and can be exacerbated by consuming potassium-rich foods. Monitoring blood pressure regularly (A) is important when taking antihypertensive medications. Reporting signs of infection (B) is crucial as ACE inhibitors can lower the immune response. Avoiding salt substitutes (C) is necessary because they may contain potassium chloride, leading to increased potassium levels, which can be harmful in combination with ACE inhibitors.

Correct Answer: C

Rationale: Verifying the blood type and Rh factor with another healthcare professional is the most crucial action to prevent a transfusion reaction. Ensuring compatibility between the donor blood and the recipient is essential in preventing adverse reactions such as hemolytic transfusion reactions. Checking vital signs is important for monitoring the client during the transfusion process but does not directly prevent a transfusion reaction. Using a blood filter can help remove clots and debris but does not address the risk of a reaction due to blood type incompatibility. Administering antihistamines before the transfusion is not a standard practice to prevent transfusion reactions related to blood type incompatibility.

Correct Answer: B

Rationale: In the management of status epilepticus, the initial medication of choice is a benzodiazepine such as lorazepam (Ativan) to rapidly terminate the seizure activity. Lorazepam acts quickly and effectively in stopping seizures. Phenytoin (Dilantin) is often used as a second-line agent for status epilepticus, and carbamazepine (Tegretol) is not typically indicated for the acute treatment of status epilepticus. Acetaminophen (Tylenol) is a pain reliever and antipyretic but is not used in the treatment of status epilepticus.

Correct Answer: A

Rationale: The correct answer is A: Improved academic performance. Physical activity has been shown to improve academic performance by enhancing concentration and cognitive function. This benefit is particularly important for elementary school students who are developing foundational skills. Choice B, increased social interactions, while important for overall development, may not directly relate to the academic aspect that the nurse is focusing on. Choice C, enhanced physical strength, is a valid benefit of physical activity but may not be as relevant to academic performance as the ability to concentrate and learn. Choice D, better sleep patterns, is also a valuable outcome of physical activity but is not as directly linked to academic performance as improved cognitive function.
